Clocking Koufax

In lieu of an abstract, below is the essay\u27s first paragraph. Walking out of the tunnels of Baltimore’s Memorial Stadium, even after the roaring crowds had departed in compressed streams of red taillights, was the best part of the evening, John Angelina had decided early in the baseball season. Especially now that the Orioles were headed for a pennant and possibly the World Series, the line of groupies would wait for the pitchers. Not that the other players or positions were any less attractive, it was just something about the pitchers. Particularly that battery of pitchers that year that would in fact find heroes in all unlikely places and circumstances; that year that would deliver a resounding win at the World Series against the legendary Los Angeles Dodgers and the brilliant Sandy Koufax

Alamogordo

In lieu of an abstract, below is the essay\u27s first paragraph. The road into Clovis had been tortuous but tinted with the colors of the New Mexico desert subtly touched by the incipient autumn. Driving a military Jeep with a comrade from their former B-17 squadrons in Europe, Joseph Angelina thought how different it would be to fly in this clear, dry air, so remarkably pure after his recent years of trying to locate enemy targets in cloudy and moody Europe

Why is economic geography not an evolutionary science? Towards an evolutionary economic geography

The paper explains the commonalities and differences between neoclassical, institutional and evolutionary approaches that have been influential in economic geography during the last couple of decades. For all three approaches, we argue that they are in agreement in some respects and in conflict in other respects. While explaining to what extent and in what ways the Evolutionary Economic Geography approach differs from the New Economic Geography and the Institutional Economic Geography, we can specify the value-added of economic geography as an evolutionary science.evolutionary economic geography, new economic geography, institutional economic geography

The spatial evolution of the British automobile industry

This paper aims to describe and explain the spatial evolution of the automobile sector in Great Britain from an evolutionary perspective. This analysis is based on a unique database of all entries and exits in this sector during the period 1895-1968, collected by the authors. Cox regressions show that spinoff dynamics, localization economies and time of entry have had a significant effect on the survival rate of automobile firms during the period 1895-1968.evolutionary economics, automobile industry, entry, exit

The effect of regional differences on the performance of software firms in the Netherlands

In this paper, we concentrate on how evolutionary economics contributes to a better understanding of the spatial evolution of newly emerging industries. Inspired by evolutionary thinking, four types of explanations are discussed and tested in an empirical analysis of the spatial pattern of the software sector in the Netherlands. Traditionally, agglomeration economies provide an explanation for the spatial concentration of an industry. Firms located in a cluster of similar or related sectors benefit from cost reductions, due to lower transportation costs, a thick labour market, specialised suppliers and information spillovers. An evolutionary approach on agglomeration economies provides an alternative view. It focuses explicit attention on knowledge spillovers as a vehicle of local diffusion of organizational routines or competences from one firm to the other. Such transfers of (tacit) knowledge are facilitated by spatial proximity of firms and a common knowledge base. In addition, an evolutionary approach takes a dynamic perspective on the role of agglomeration economies. During the initial stage of development of a new industry, the surrounding environment is still directed to routines and competences related to existing industries. When the new industry concentrates in a particular area to a considerable degree, a supportive environment (specialized knowledge, labour with specific skills) may gradually come into being, and localization economies may arise. Other evolutionary mechanisms may also provide an explanation for the spatial formation of new industries. We distinguish another three of them. First of all, transfer of knowledge and successful routines between firms in an emerging industry may occur through spin-off dynamics. Secondly, (social) networks may function as effective channels of knowledge diffusion and interactive learning, because they can provide a common knowledge base and mutual understanding and trust. Thirdly, firms in new industries with organizational capabilities that can deal effectively with the lack of required resources (such as knowledge, skills and capital) may become dominant, due to selection and imitation. Based on cross-sectional data gathered among 265 software firms in the Netherlands in 2003, we have tested which factors have influenced the innovative productivity of these firms. Using regression techniques, the outcomes suggest that spin-offs and firms with organizational capabilities perform better, while networks relations do not seem to affect the performance of software firms. Geography matters as well: software firms located in a region with a labour market with more ICT-skills show a higher innovative productivity.Evolutionary economics, industrial location, evolution of industries, software sector, agglomeration economies, organizational capabilities, spin-off, networks

Moduli Spaces of Fivebranes on Elliptic Calabi-Yau Threefolds

We present a general method for calculating the moduli spaces of fivebranes wrapped on holomorphic curves in elliptically fibered Calabi-Yau threefolds, in particular, in the context of heterotic M theory. The cases of fivebranes wrapped purely on a fiber curve, purely on a curve in the base and, generically, on a curve with components both in the fiber and the base are each discussed in detail. The number of irreducible components of the fivebrane and their properties, such as their intersections and phase transitions in moduli space, follow from the analysis. Even though generic curves have a large number of moduli, we show that there are isolated curves that have no moduli associated with the Calabi-Yau threefold. We present several explicit examples, including cases which correspond to potentially realistic three family models with grand unified gauge group SU(5).Comment: 56 pages, latex2e with amsmath and epsfig, 9 postscript figure
